Dualism

Dualism, in religion, the doctrine that the world (or reality) consists of two basic, opposed, and irreducible principles that account for all that exists. It has played an important role in the history of thought and of religion.

Nature and significance

In religion, dualism means the belief in two supreme opposed powers or gods, or sets of divine or demonic beings, that caused the world to exist. It may conveniently be contrasted with monism, which sees the world as consisting of one principle such as mind (spirit) or matter; with monotheism; or with various pluralisms and polytheisms, which see a multiplicity of principles or powers at work. As is indicated below, however, the situation is not always clear and simple, a matter of one or two or many, for there are monotheistic, monistic, and polytheistic religions with dualistic aspects.

Various distinctions may be discerned in the types of dualism in general. In the first place, dualism may be either absolute or relative. In a radical or absolute dualism, the two principles are held to exist from eternity; for example, in the Iranian dualisms, Zoroastrianism and Manichaeism, both the bright and beneficent and the sinister and destructive principles are from eternity.

In a mitigated or relative dualism, one of the two principles may be derived from, or presuppose, the other as a basis; for example, the Bogomils, a medieval heretical Christian group, held that the Devil is a fallen angel who came from God and was the creator of the human body, into which he managed by trickery to have God infuse a soul. Here the Devil is a subordinate being and not coeternal with God, the absolute eternal being. This, then, is clearly a qualified, not a radical, dualism. Both radical and mitigated types of dualism are found among different groups of the late medieval Cathari, a Christian heretical movement closely related to the Bogomils.

Another and perhaps more important distinction is that between dialectical and eschatological dualism. Dialectical dualism involves an eternal dialectic, or tension, of two opposed principles, such as, in Western culture, the One and the many, or Idea and matter (or space, called by Plato “the receptacle”), and, in Indian culture, maya (the illusory world of sense experience and multiplicity) and atman-brahman (the essential identity of self and ultimate reality). Dialectical dualism ordinarily implies a cyclical, or eternally repetitive, view of history. Eschatological dualism—i.e., a dualism concerned with the ultimate destiny of humanity and the world, how things will be in the “last” times—on the other hand, conceives of a final resolution of the present dualistic state of things, in which evil will be eliminated at the end of a linear history constituted of a series of unrepeatable events instead of a cyclical, repetitive one. The ancient Iranian religions, Zoroastrianism and Manichaeism, and gnosticism—a religio-philosophical movement influential in the Hellenistic world—provide examples of eschatological dualism. A type of thought, such as Platonism, that insists on a profound harmony in the cosmos, is thus more radically dualistic, because of its irreducibly dialectical character, than Zoroastrianism and Manichaeism, with their emphasis on the cosmic struggle between two antithetical principles (good and evil). Midway between these extremes is gnostic dualism, which has an ontology (or theory of being) of an Orphic-Platonic type (see belowAmong ancient civilizations and peoples) but which also affirms the final disappearance and annihilation of evil with the eventual destruction of the material world—and thus comprises both dialectical and eschatological dualism.

In philosophy, dualism is often identified with the doctrine of transcendence—that there is a separate realm or being above and beyond the world—as opposed to monism, which holds that the ultimate principle is inside the world (immanent). In the disciplines concerned with the study of religions, however, religious dualism refers not to the distinction or separation of God and the world but to the doctrine of two basic principles, a doctrine that, moreover, may easily be compatible with a form of monism (e.g., Orphism or the Advaita school of Vedanta) that makes the opposition between the One and the many absolute and sees in multiplicity merely a fragmentation (or illusory obliteration) of the One.

Historical varieties of religious dualism

Among ancient civilizations and peoples

Dualism is a phenomenon of major importance in the religions of the ancient world. Those of the Middle East will be considered here.

Egypt and Mesopotamia

While there was generally no explicit dualism in ancient Egyptian religion, there was an implicit dualism in the contrast between the god Seth and the god Osiris. Seth, a violent, aggressive, “foreign,” sterile god, connected with disorder, the desert, and loneliness, was opposed to Osiris, the god of fertility and life, active in the waters of the Nile. Seth also possessed some typically dualistic marks of a mythological character: his action, as well as his personality itself, was ambivalent; and, as a typical trickster, he was also capable, at times, of constructive action in the cosmos. The myths of Osiris and Seth may be compared in various ways with those recently discovered among the Dogon people of the western Sudan, which contrast Nommo, a fertile and happily mated primordial being pictured in fish form, with Yurugu (“Pale Fox”), an unhappy, sterile character who lives in the wilderness without a mate. Yurugu is considered to be the element that makes the universe complete (the same role assigned to Seth in the Egyptian myth).

Dualism, broadly speaking, was also present in ancient Mesopotamian religion. In myths pertaining to the origin of the gods and of the cosmos, the opposition between the primordial deities (Apsu, the Abyss, and Tiamat, the Sea) and the new ones (particularly Marduk, the demiurge, or creator) displayed some dualistic aspects. Though the earlier deities had established the basic reality of the universe—its ontological core—because of their chaotic and selfish nature they resisted their own offspring, who were later to create the now existing definite order of the cosmos. A dualism of the ontological—basic reality or being—versus the cosmological—the form or order of the material universe—is thus implicitly affirmed.

Greece and the Hellenistic world

Analogous dualistic concepts may be found in the early GreekTheogony of Hesiod in his myths of the gods Uranus, Cronus, and Zeus and the conflict between primordial and later gods. It was in the later, Classical Greek world, however, that dualism was most evident. Many of the pre-Socratic philosophers (6th and 5th centuries bce) were dualistic in various ways. In the teachings of Parmenides, for example, noted for reducing the world to a static One—a classical instance of monism—there is still a radical opposition between the realms of Being and Opinion—between ultimate reality and the world of human sense experience. On the other hand, in the doctrines of Heracleitus, noted for reducing the world to fiery Change, the conflict of opposites (hot-cold, day-night, beginning-end, the-way-up–the-way-down), called by Heracleitus polemos (“war”), was exalted to become a metaphysical principle. Though these opposites are piecemeal dyads, their effect taken together is as a whole dualistic. The dualism of Empedocles, simultaneously a religious teacher and a natural philosopher, is especially striking, for he viewed the primordial sphere of the universe as undergoing cycles alternately under the dominance of the antithetical principles of Love and Discord, which periodically break and then reconstruct it. In this context there exist daimones (“souls”), divine beings that have fallen from a superior world into this world and exist clothed in the “foreign robe of the flesh.” These souls are therefore subject to transmigration through a series of vegetable, animal, and human bodies, owing to a primitive accident for which credit was given “to the furious Discord.”

The same antithetical principles are to be found in Orphism, a Greek mystical school, which constituted an independent development within Greek religion and philosophy; beginning in the 6th century bce, it was part of a “mysteriosophic” trend that sought to attain the wisdom of secret mystic and cultic doctrines. Orphism is characterized by its sōma-sēma, or body-tomb concept, which saw the body as a prison or tomb in which the soul—a divine element akin to the gods—is incarcerated. In addition to this psychophysical dualism of soul and body, the Orphic idea that “everything comes from the One and returns to the One” demonstrates a typical dialectical dualism, in which an implicit monism is involved. Developing on an analogous level, Pythagorean numerical and mystical speculation—arising from the 6th-century-bce Greek philosopher and religious teacher Pythagoras—also stressed the dualistic opposition of Monad-Dyad (One-Two) and of other dialectical pairs of opposites.

Many of these dualistic ideas, especially the Orphic and Pythagorean ones, are also found in writings of the Greek philosopher Plato, such as the Timaeus, Phaedo, Gorgias, and Cratylus. In these writings a divine part of the human soul that is directly infused by the divinity and a mortal part (passionate and vegetative) are defined and considered. The mortal part is assigned to humanity by inferior divinities, charged to do so by the supreme divinity; and the appetitive passions involved, if followed, are held to be responsible for the punishments that the soul will suffer during various periods of habitation in the other world and reincarnations in this one. Thus, God remains free of blame for human destiny. The mortal or spoiled part of humanity is further attributed, in Plato’s Laws, to the “titanic nature” within its makeup—an element of violence and impiety inherited from the primordial rebellious Titans, sons of the Earth.

Plato’s notions of humanity were rooted in both ontology and cosmology—i.e., in views on being and on the orderly structure of the universe. In the Timaeus he considers the cosmos as a single harmony, which for the sake of completeness requires the existence of inferior levels that are bound not only to matter but also to Necessity (the realm of things that could not have been otherwise and that are hence not amenable to divine activity). A different view is found in his Laws, which describes two “Souls” of the World, one of which causes good and one evil. The Politicus is concerned with two eternally recurring alternating cycles in the cosmos, with successive epochs guided either by the gods or by humans.

Plato’s central inspiration, which unifies his metaphysics, his cosmology, his anthropology, and his doctrine of the soul, was basically dualistic (in the sense of dialectical dualism) with two irreducible principles: the Idea, or form, and the chora (or material “receptacle”) in which the Idea impresses itself. All of this world is conditioned by materiality and necessity, and because of this, the descent of souls into bodies is said to be rendered necessary as well.

Neoplatonism, a 3rd-century-ce development from Plato’s thought, conceived the cosmos as a harmony with a succession of levels emanating from an ultimate unit. There was in the system, nevertheless, a rupture of the harmony of the cosmos called tolma (“the audacity”), which served as an explanation for the descent of Soul into the material world—and thus constituted a dualistic element.

In gnosticism, a Hellenistic religious movement that entered original Christianity from earlier pagan sources and that viewed matter as evil and spirit as good, dualism manifested itself in a more dramatic way. Gnostic dualism cannot be understood without reference to both Judaism and Christianity, and perhaps even to Zoroastrianism, since gnostic eschatological characteristics were derived from them. Gnosticism was also connected with certain principles of Orphism and Platonism; reflecting the Orphic body-tomb doctrine, for example, gnosticism adopted a firmly antisomatic stance (against the body) and similarly adopted the concept of the divine soul—the pneumatic, or spiritual, soul, as the gnostic would say, of the same substance as the divinity—that is destined to free itself from the tyranny of a material, cosmic demiurge (or subordinate deity). Certain gnostics, moreover, developed a radical anticosmism in which they registered their animosity against the material universe by cursing the stars—which brought them bitter reproach from Plotinus, the founder of Neoplatonism. As viewed by the gnostic Ophite sect, which venerated the ophis (“snake”) as a symbol of knowledge, the cosmos comprises three parts: the superior world, the inferior world (material and chaotic), and the intermediate world, or logos (“word” or “reason”)—the logos being depicted as a snake that impresses spiritual forms into the chaotic matter. These forms—life, soul, and vital masculine substance—are later freed again, a liberation that completely empties the material world.

Such gnostic views are of two types: Iranian and Syrian-Egyptian. Iranian gnosticism is characterized by an absolute, radical dualism: light and darkness, pneuma (“spirit”) and chaotic formless matter, oppose each other from eternity. Syrian-Egyptian gnosticism is characterized by a dualism that is mitigated (as earlier defined) but also drastic: the inferior world, the chaotic darkness, begins to exist only at a special moment owing to an accident in the divine world, and this accident is usually also identified with an “audacity,” a defect in one of the “aeons,” or divine entities.

Iran

In the Indo-Iranian period (2nd millennium bce) there were already tendencies toward dualistic thought, especially in myths relating to monstrous and demonic beings who still the movement of the waters and thus make cosmic life impossible. In later archaic Indian speculation there was also a tendency to oppose devas (“gods”) to asuras (“demons”). Iranian dualism, however, expressed itself most characteristically in Zoroastrianism. In the Zoroastrian religious texts, the Gāthās, there is an opposition between two spirits, the Beneficent Spirit (Spenta Mainyu) and the Destructive Spirit (Angra Mainyu, or Ahriman). These two spirits are different, irreducible principles; at the beginning they have chosen life and nonlife, respectively. Though the Beneficent Spirit is almost a hypostasis (the substance) of the divinity (Ahura Mazdā, or Ormazd), nothing is said in the Gāthās about the origin of the Destructive Spirit. In any case, the very fact that the Destructive Spirit is said to be the “twin brother” of the Beneficent One does not imply that he is a son of Ahura Mazdā but implies only that the two spirits are “symmetrical”—i.e., equal and contrary as to their respective efficacy and orientation.

Medieval Zoroastrian treatises present radical and eschatological dualisms in their extreme forms. According to the Bundahishn (“Primordial Creation”) text, Ormazd and Ahriman have always existed. Ormazd is represented as lofty, in the light, full of omniscience and goodness, while Ahriman is represented as debased, in darkness, full of aggressiveness and ignorance. Ormazd’s omniscience allows him to conceive and to actualize the Creation and Time, because only these can offer him an arena in which to accost Ahriman and eliminate him.

The medieval Zoroastrian treatises also describe another dual formulation, the two realms of creation and of reality: the mēnōk (“potential, embryonic, initial, heavenly, and invisible”) and the gētīk (“realized, final, worldly, concrete, and visible”). But this opposition does not imply a devaluation of the gētīk, of this world.

Zurvanism, a Zoroastrian heretical movement (c. 3rd/4th century bce–7th century ce), was also dualistic. The very names of Zurvān (Time-Destiny) and the partially synonymous zamān (“time”) already appear in the later Avesta and in medieval treatises, in which Time is the milieu in which Ormazd and Ahriman fight. Also, a myth attributed to Zoroastrian priests by later, non-Iranian sources speaks of Zurvān as the father of Ormazd and Ahriman. At times Zurvanite mythology tends toward formulations of a gnostic and Manichaean type (women paid allegiance, for example, to Ahriman, who has partial authority in the world). Zurvanism also developed theosophic characteristics (involving mystical insights), such as that which discerned the ambivalence of Zurvān—namely, that although an evil element (an evil thought or spiritual corruption) has always existed within him, he nonetheless, so it seems, eliminates the evil by expressing it and is thus worthy to be identified with the supreme divinity (Yazdān).

Among South and East Asian religions

Dualisms have also appeared in various forms in the religions of India and China.

India

Indian dualism has involved the opposition of the One and the many, of reality and appearance. In an ancient Hindu hymn (Rigveda, 10.90), Purusha, the ancient primordial Man and “the Immortal that is in heaven,” is opposed to this world. The three quarters of Purusha that comprise the transcendent world are opposed to the other quarter of him (his limbs) that is this world; i.e., the divine foundation, the divine substance of this world, is made out of his limbs. Early speculation on the identity of the atman (“self”) and brahman (the very core of reality), as opposed to the material and visible world that is subject to maya (“mundane illusion”), has been mentioned above.

The Samkhya school of Indian philosophy presents another, probably later, formulation of dualism based on two eternal and opposed cosmic principles: prakriti (“original matter”) and purusha (“spirit”). Matter is differentiated into three different gunyas (“qualities”) that articulate the three levels of the being and essential nature of humanity in hierarchical connection with each other. Spirit, in itself free, eternal, and infinite, becomes involved in matter by the development of the latter. Salvation coincides with the knowledge of the state of things: “I (spirit) am one thing and It (matter) is another.”

Classical Chinese thought—which began with the teaching of the philosopher Confucius (flourished early 5th century bce) and ended with the close of the Warring States period in 221 bce—upheld the notion of a dynamic universe and thus generally eschewed the radical dualism that emerged in India, Iran, and Europe. The notion of yinyang, the opposed polarities of cosmic flux, may at first seem dualistic: yin is associated with passivity and femininity, yang with activity and masculinity. Yet yin and yang are not radically separate; they complement and permeate each other, emerging as two extreme aspects of the constant transformation of the Dao (the “Way” of the universe). Likewise, all of the ten thousand things (a Chinese metaphor for the world) are seen as the cumulative product of the generative forces of heaven and earth (tiandi). Like yin and yang, however, heaven and earth are complementary aspects of a continuous process of creation and not radically separate entities.

A more extreme dualism appeared as Chinese thinkers encountered intellectual systems—most notably, Buddhism—that originated outside China. Even so, the emphasis in Chinese thought remained primarily on harmony, rather than tension, between opposites. Wang Bi (226–249), who developed much of the terminology and many of the concepts of Chinese ontology, distinguished being (you) from nonbeing (wu), the latter of which he equated with the Dao. Rather than nothingness, however, nonbeing is pure being. Wang referred to wu as the “Great Note” that harmonizes the other notes (beings) that constitute the symphony of the universe.

The philosophy of the neo-Confucian thinker Zhu Xi (1130–1200), which subsequently influenced greater East Asian culture, gave rise to controversies between dualistic interpretations of his system. Zhu stated that the universe and everything in it is a combination of li (principle, but also connoting a concept akin to natural law; literally “pattern”) and qi (life force or matter energy; literally “vital breath”). When principle combines with matter-energy, a thing exists. For Zhu, principle and matter-energy are obverse sides of the same coin: both are generated by the fluctuations of the Great Ultimate (taiji). Yet, while he insisted that principle and matter-energy are never separate, Zhu seemed to give ontological priority to principle, which provides order to dynamic, chaotic matter-energy. The question of the relationship between li and qi generated intense debate among neo-Confucian thinkers not only within China but also in Korea and Japan.

Among religions of the West

No real dualism is found in Judaism, except in the gnostic and theosophic forms of Jewish mysticism known as Kabbala. The presence of a vigorous and universal monotheism implies not only faith in a single creative god but also faith in a god who is the uncontested master of history, and neither Satan nor Belial detracts from this absolute monotheism. Within these limitations, however, a tendency toward dualistic thought can be seen in such late noncanonical texts as the First Book of Enoch (c. 1st century bce), in which certain angels are said to have fallen as a consequence of their wedding with the daughters of human beings. These angels, it is held, taught humans the malevolent arts of magic, seduction, and violence, together with such elements of culture as writing and the use of metals. Though there is no dualism in the proper sense in the Manual of Discipline, one of the Qumrān texts of the Dead Sea Scrolls, a certain polarity is nonetheless displayed in a passage that asserts of God that

he created man to have dominion over the world and made for him two spirits, so that he may walk by them until the time of his visitation: they are the spirits of truth and error. In the dwelling of light are the origins of the truth, and from a spring of darkness are the origins of error. In the hand of the Prince of Lights is dominion over all the children of righteousness, in the ways of light they walk. And in the hand of the angel of darkness is all dominion over the children of error; and in the ways of darkness they walk.

The context of this passage, however, is completely monotheistic. It expresses a doctrine also found in the Didachē, a Jewish-Christian work of the early 2nd century ce (better known as the Teachings of the Twelve Apostles), that of the two roads on which an individual may walk, the good road and the bad, the road of life and that of death, with God leaving the choice of the road to one’s free will. It also expresses the later rabbinic doctrine of the struggle between the good and evil inclinations (yetzer) within each human. There is also no hint of dualism in the two “sources” mentioned in the Qumrān texts, the bright source and the dark. These are hardly dualistic principles (in the ontological sense of the term) but are simply radical (i.e., original) polarities in spiritual orientation. (Not even the “Angel of Darkness,” mentioned in the same context, is a principle, though he is a person and a power.)

There is thus no true parallelism with the two principles that appear in Iranian Zurvanism. Elements of dualistic thought (in a Platonic sense) are also found in the works of the Jewish Hellenistic philosopher Philo of Alexandria (1st century ce), whose philosophy was dualistic in its doctrines about the universe and humanity but without shaking his basic adherence to biblical monotheism.

In Christianity, dualistic concepts appeared principally in its gnostic developments. But even in the 2nd-century Judaizing sect of the Encratites, which was not really gnostic, there were dualistic aspects that had modified some tendencies of later Judaism. These teachings were also particularly prominent in the writings of the supporters of Docetism (the doctrine that Christ, being divine, did not suffer and die; 2nd century), who held that matter is essentially evil and that the soul is a preexistent substance. According to the Encratites, the preexistent soul, once it “gets effeminated by concupiscence,” drops into the carnal world. Since generation perpetuates the soul’s state of decay in this bodily world, the Encratites condemned all sexual relations.

The dualism of Marcion (a 2nd-century semi-gnostic Christian heretic) was really a ditheism (a system positing two gods), though common gnostic presuppositions—such as antisomatism and anticosmism, the condemnation of the body and the material universe—were also present in his thought. For Marcion, the God of the Hebrew Bible (Old Testament) is an inferior and harsh creator demiurge, author of the world and of humankind, who is nonetheless completely distinct from the supreme divinity, who manifested himself in Jesus and is a stranger to this world.

For Saturninus (or Satornil) of Antioch, the founder of a 2nd-century Syrian gnostic group that was commonly connected with the tradition of Simon Magus (reputed leader of an earlier gnostic sect), the God of the Hebrew Bible is only one of the angels, the martial angel of the Judaic nation, although (as with Marcion) he is distinct from the Devil, who is in fact his opponent. According to Saturninus, a primordial accident caused a wave of pneuma (“spirit”) to land in the inferior darkness, where it is said to have remained prisoner and now continues its existence in those who, characterized by the presence in them of this superior element, will later be conducted back to their heavenly origin by Jesus, a messenger coming from above.

Conceptions of a similar type are also found in the “Psalm [or Hymn] of the Naassenes” (Naassene is the Hebrew term for Ophite, mentioned above) and in the “Song of the Pearl” in the gnostic Acts of Thomas; here also occurs the concept of a “saviour to be saved,” who has been sent from above and was made a prisoner by darkness. This basic concept was developed fully only in Manichaeism.

The gnostic-dualist view survived in late antiquity and into the Middle Ages, both in the East, among the Mandaeans, Yazīdī, and some extreme sects within the Shīʿite branch of Islam, and in the West, among the Bogomils and Cathari. It is still present today in modern theosophy.

Among religions of modern indigenous peoples

Religious dualism also manifests itself among nonliterate peoples, especially in the concept of a “second” figure, an ambivalent demiurge-trickster who can be both a collaborator and a rival of the supreme being and independent of the latter in origin. Such tricksters include the Coyote (in North American Indian mythology), the Raven (among Paleo-Siberians), and the Crow (among the Southeast Australian tribes). To these animal figures are attributed the origin of such negative aspects of life as death and illness. But they are also credited as benefactors—e.g., in creating utilities in the cosmos and in the invention of fire. The demiurge-trickster is typically ambivalent, tremendously frightful and efficacious, but also frequently limited in power. For example, such tricksters are often incapable of animating the beings that they have molded and must therefore request the help of the supreme being in bringing them to life. They are said to be selfish, lonely, and unhappy, and because of these qualities they are moved, despite their arrogance, to attempt to relate themselves to or unite with the supreme being.

A typically dual composition (involving the coexistence and cooperation of two elements), or even a dualistic opposition (as two opposed elements that function as principles in respect to the actual creation), is found in the Dogon (western Sudanese) notions about Nommo and Yurugu, already mentioned. A series of words refers to both principles; i.e., a series of realities and categories can be named that constitute the world in its functional variety, which transcend the simple good-evil opposition, and according to which both Nommo and Yurugu are dualistic “principles” essential to the actual dynamics of the world.

Other dualistic concepts among indigenous peoples posit opposite the supreme being a violent and death-bearing second figure of a demiurgical type. The character of Erlik in the mythologies of the Central Asiatic Turks (e.g., among the Altaics) is typical.

Erlik is a king of the dead and master of death who assumes the role of a fraudulent and unfortunate collaborator with the supreme being. In stories about the origin of the universe, he appears as an aquatic bird in charge (under the supreme being) of fishing a little earth from the bottom of the primordial sea—a theme also well-known in eastern European folklore. In other myths, a similar being spits on human beings at the time they are created by God or breathes his bad spirit into man or woman. Elsewhere there is depicted an opposition of twin brothers, of whom one is the demiurge-creator of good things and the other of death; both, however, are the sons of a mother goddess of heavenly origin. This pattern is exemplified in the Iroquoian myth of Yoskeha and Tawiskaron—a myth curiously reminiscent of certain aspects of the Iranian Zurvanite mythology.

Other ethnological polarities, or pairs of opposites (eastern-western, celestial-terrestrial, solar-lunar divinities, right-left, full moon–dark moon, and so on) are dualistic in the sense of contrasting principles or creating agencies.
